We followed the instructions to get to the listing but there was no keycard in the mail box as stated, so I called the host (who was very helpful on the phone) and it was delivered via grabbike in around 25 minutes which caused slight inconvenience as we had to wait at the lobby. The entrance lock to the room requires you to hold and tap for a few seconds, and you will see 2 digits and a * that you gave to press before keying in your 4 digit code provided.
The apartment was nice and cozy and there are many restaurants and massage areas nearby, and the nearest bts takes 12 mins walk - make sure you take the right exit (with the gin restaurant) or you end up walking around - one big round.
Overall a good value stay.
